FBM201輸入輸出模塊
是一種含有儲能裝置的不間斷電源系統(tǒng)，將蓄電池（多為鉛酸免維護(hù)蓄電池）與主機相連接，通過主機逆變器等模塊電路將直流電轉(zhuǎn)換成市電的系統(tǒng)設(shè)備。
斷電往往是突發(fā)的，且較為頻繁。UPS能夠提供持續(xù)、穩(wěn)定、不間斷的電源供應(yīng)，在市電出現(xiàn)異常時，有效地凈化市電，在市電與負(fù)載之間，形成電能的“守護(hù)墻”。
UPS按應(yīng)用場景可分成工業(yè)使用型工頻機和機房數(shù)據(jù)中心使用型高頻機兩種。
FBM201輸入輸出模塊工頻機：
采用工頻變壓器作為逆變升壓部件的UPS俗稱工頻機（對應(yīng)國外的TRANSFORMER BASED UPS），主要由整流器、電池組、逆變器和升壓變壓器組成。工頻機的主要特點是逆變器輸出端有一個升壓變壓器，能把逆變器的輸出電壓升至380V，而其直流母線電壓通常較低。
工頻UPS多采用SCR可控硅整流器，常見的有6脈沖整流器和12脈沖整流器。為了提高輸入功率因數(shù)、降低整流器對前級電網(wǎng)的諧波污染，需在輸入端加入濾波裝置，一般采用無源濾波器、有源濾波器或有源加無源混合型濾波器來解決工頻機輸入諧波較大的問題。
高頻機：
利用高頻開關(guān)技術(shù)，以BOOST直流升壓電路將直流母線電壓升至800V左右，從而替代逆變器輸出側(cè)工頻變壓器的UPS，俗稱高頻機（對應(yīng)國外的TRANSFORMERLESS UPS），它主要由整流器、電池組、DC升壓裝置、逆變器組成。高頻機的主要特點是沒有變壓器，采用高頻化IGBT整流器，直流電壓高，電池節(jié)數(shù)多，重量較輕，體積較小。
高頻UPS無需增加濾波器，即可提高輸入功率因數(shù)并降低整流器對前級電網(wǎng)的諧波污染。
工頻機與高頻機的區(qū)別
工頻UPS與高頻UPS的差異主要體現(xiàn)在輸入電流諧波、輸入功率因素、整流器技術(shù)、有無變壓器、整機效率幾個方面。
■ 兩者的主要差異：
（1）工頻UPS內(nèi)置隔離變壓器，技術(shù)成熟，某些產(chǎn)品占地面積甚至小于高頻機（IGBT高頻化UPS受制于元器件的容量，通常采用小功率模塊并聯(lián)方式實現(xiàn)500KVA，體積較大）；
（）高頻UPS由于采用IGBT整流技術(shù)，其輸入諧波及輸入功率因素方面較有優(yōu)勢，由于采用直流升壓電路提高了內(nèi)部直流電壓，因此無需輸出變壓器。higher requirements are put forward for the load-bearing capacity and safety reliability of tires. The manufacturing process of tire mainly includes three steps: first, different kinds of rubber, different oils, dyes and additives are mixed together to produce different parts of tire, such as liner, edge and tire surface. At the same time, it also needs to produce other parts, including steel strip required by tire; Next, the various parts of the tire are assembled through the tire forming equipment; Finally, the tire is fixed after heating and vulcanization. In this process, tire assembly is one of the most critical processes, and tire forming equipment has become the equipment that all tire manufacturers attach great importance to. Qingdao University soft control company is one of the professional manufacturers of radial tire forming equipment. Their customers include Hangzhou Chaoyang, Henan Fengshen, Liaoning Langma, Shandong Jinyu, Hengfeng, Sailun, Huanghai, Pingdu Guangming, etc. In order to help tire manufacturers produce high-quality tires faster and better, Qingdao University soft control company is committed to producing highly reliable tire forming equipment for the production of all steel radial truck tires.
